What SymPy Live does is return the LaTeX string of expression using the LaTeX printer (accessible through the latex() function), and then passes that to MathJax, which converts it to a printed expression. Any string output is passed to MathJax, so even if you just enter a string, it will be parsed as LaTeX.
If you want to know how the LaTeX printer works, see sympy/printing/latex.py.
